Problem with Website Embedding

[Eugen Besel]

Hello together,

I have a small GWTP App which uses gwt(2.8.0-beta1) and gwtp 1.5.2. this app should be embedded into another html page.
So I took a look into gwtp docu and implemented MyRootPresenter with:

public class MyRootPresenter extends RootPresenter {

    private static final Logger LOG = Logger.getLogger(MyRootPresenter.class.getName());

    public static final class MyRootView extends RootView{
        @Override
        public void setInSlot(Object slot, IsWidget content) {
            LOG.info("enter SetInSlot in MyRootPresenter");
            RootPanel.get("mainContent").add(content);
        }
    }

    @Inject
    public MyRootPresenter(EventBus eventBus, RootView view) {
        super(eventBus, view);
    }
}

and ClientModule with
bind(RootPresenter.class).to(MyRootPresenter.class).asEagerSingleton();

I'm not sure, whether it works, because:

If I don't have any div element in my index.html with id = "mainContent", then I still can see my application. (I would expected, that some error occurs)
I add a log into the method setInSlot in MyRootPresenter und set a breakepoint, but neither log nor breakepoint fired. It seems for me, that the application don't go to the setInSlot.

Can you please tell me what should I do? I have also following code in my application:

RootPanel.get("mainContent").getElement().getAttribute("data-customerId");

on this point exception fired, that RootPanel.get("mainContent") doesnt exist.

thank you very much.

It appears that what you're doing is overriding the view's setInSlot, which only applies when setting things in the presenter/view's slot, not setting the location of the presenter and view themselves.

I'm not sure of the best way to set a GWTP app in a specific element on a page, I've only used it as a full SPA, but maybe that will help a bit.

I found what I have implemented wrong :)

Constructor of MyRootPresenter should inject the new class MyRootView and not the old RootView.
